In this study, we developed an analytical model of slot-loaded rectangular microstrip patch antennas based on the simulation results by varying slot parameters. The dominant resonant frequency predicted by such a model is in strong agreement with the experimental results measured at several locations of slot-loaded rectangular microstrip patch antennas. The model enables a reliable and quick computation of the resonant frequency, which generally follows a harmonic behavior that nearly resembles the resonant frequency of a microstrip antenna without a slot, which can be related to a small change in the impedance caused by the slot position. Results showed a good agreement between simulations and measurements for all the slot positions. Mathematical analytic functions to describe the changes in specific characteristic parameters of the slot-loaded rectangular microstrip patch antennas are also included.

ABSTRACTSemi-insulating (SI) silicon carbide (SiC) was evaluated as a candidate material for dielectric substrate for patch antennas suitable for monolithic antenna integration on a SiC semiconductor chip. Computer simulations of the return loss were conducted to design microstrip patch antennas operating at 10 GHz. The antennas were fabricated using SI 4H-SiC substrates, with Ti-Pt-Au stacks for ground planes and patches. A good agreement between the experimental results and simulation was obtained. The radiation performance of the designed SiC based patch antennas was as good as that normally achieved from antennas fabricated using conventional RF materials such as FR4 and Rogers. The antennas had the gain around 2 dBi at 10 GHz, which is consistent with the conventional antennas of a similar size.

Slot Cutting

In this paper, the performance of U-slot Rectangular Microstrip Patch Antennas (RMSA) is analyzed by using different flexible substrates. The RMSA is designed to operate for a resonant frequency of 2.45 GHz with flexible substrate materials like Polydimethylsiloxane (PDMS), GML-1032 and Polyethylene. The antenna parameters like reflection coefficient, voltage standing wave ratio (VSWR), radiation pattern, bandwidth and cost are analyzed by keeping all the substrate height same and the value is 2.5mm. U-slot cutting is used in the patch to overcome the narrow bandwidth limitation in RMSA because U-slot tunes the higher order orthogonal mode resonance frequency of the patch with respect to fundamental mode to realize the wider bandwidth. The maximum bandwidth of 80MHz is achieved with the use of PDMS. The antenna is simulated using HFSS software.

Rectangular Microstrip Antenna

Selecting an appropriate substrate material for the design of microstrip patch antenna for various applications is a very important step in antenna design. This paper presents a work of various substrates materials used for the design of low cost inset feed rectangular microstrip antenna for WLAN, WiMax, LTE, C-band and X-band applications. The substrates used are FR-4 epoxy, foam, polyethylene terephthalate (PET) and polydimethylsiloxane (PDMS). The antennas were designed, optimized and simulated using HFSS 15.0. Return loss, voltage standing wave ratio and gain analysis is carried out for these antennas. The measurement of reflection coefficient of the fabricated antennas is done using Agilent PNA-L series vector network analyzer. The simulated and measured results are well in agreement. The analysis show that antenna with foam substrate offers the lowest return loss of - 41.28 dB. Larger bandwidth and gain of 4.38 dB is observed with PET substrate.

Mutual Coupling Reduction

A mutual coupling reduction method between microstrip antenna array elements is proposed by using periodic L-loading E-shaped electromagnetic band gap structures. Two identical microstrip patch antennas at 2.55 GHz are settled together and used to analyze the performance of the designed two-element antenna array. The two antenna elements are settled with a distance of about0.26λ. To reduce the mutual coupling, the L-loading E-shaped electromagnetic band gap structures are used between these antenna elements. The simulated and measured results show that the isolation of the antenna array reaches 38 dB, which has a mutual coupling reduction of 26 dB in comparison with the antenna array without the decoupling structures.

In today’s world, the requirement for lower-weight, low-cost, low-profile, and effective-use transmitters is growing by the day. For addressing these parameters in a variety of applications, microstrip patch antennas are more popular than other antennas. The main issue with these types of microstrip patch antennas is that they have a high return loss, VSWR, and bandwidth, but these issues can be rectified utilizing a design technique. The method of design was to use mirror image layouts, which was a simple and easy way to improve performance. The efficiency of a simple patch cannot be influenced by any single structure that lacks a mirror reflection. In this study, the two +-shaped constructions are used, and the results are in good agreement. In today’s world, these antennas have a variety of uses, including WLAN and s band applications. In the future, various frameworks will be used to improve the results that have been produced thus far.
